Description

Technical Field

[0001] The present invention relates to the technical field of decorative films, and more particularly to a highly weather-resistant decorative film and a processing system thereof. Background Art

[0002] Decorative film is a new type of decorative material made of high molecular polymer as raw material, adding various additives, calendering and compounding. It can be compounded with wood, plastic board, aluminum board, iron board and other substrates to make multi-purpose decorative materials, which are widely used in various fields. The pressure-sensitive adhesive layer, coloring layer and transparent layer on some existing decorative films are relatively soft, which makes the decorative film easy to deform, and the tensile strength of the decorative film is not high. It is very easy to produce irreversible deformation due to excessive traction of the finished decorative film during the winding process of the finished product due to transmission traction.

[0003] After searching, it was found that the announcement was CN116238219B, a highly weather-resistant and non-discoloring decorative film and processing equipment, which relates to the technical field of decorative films. The decorative film includes a base film layer one, a thermoplastic resin layer, a reinforcement layer and a base film layer two. The base film layer one, the thermoplastic resin layer, the reinforcement layer and the base film layer two are bonded together in sequence by hot pressing. By hot pressing the reinforcement layer inside the decorative film, the problem of the easy deformation of some existing decorative films is solved.

[0004] However, the above-mentioned highly weather-resistant and non-discoloring decorative film has a weak simulated texture. When the decorative film is unfolded, the front and back sides of the decorative film stick to each other, affecting its use. At the same time, the base film layer 1, thermoplastic resin layer, reinforcement layer and base film layer 2 of the above-mentioned decorative film are sequentially bonded together by hot pressing, and the operation process is relatively cumbersome, which reduces the delivery efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a highly weather-resistant decorative film and a processing system. By printing an ink layer on the surface of a first polyvinyl chloride film, the simulation texture of the decorative film is improved and the variety of materials suitable for lamination is broadened. By setting a mesh woven reinforcement layer, the deformation resistance of the decorative film is improved. By coating a polyurethane resin chemical separation layer on the bottom surface of the second polyvinyl chloride film, when the roll product is opened, the front and back sides of the decorative film do not adhere to each other, thereby improving the practicality of the decorative film. By the linkage cooperation between the various components, the synchronous hot pressing and gluing operation of the upper film part, the thermoplastic resin layer and the lower film part is realized, the operation process is optimized, and the processing efficiency of the decorative film is improved.

The rotation of the glue roller 44 drives the glue coating roller 46 attached thereto to rotate, and the glue coating roller 46 and the winding roller 15 corresponding to the thermoplastic resin layer 2 rotate synchronously in the same direction, and the glue on the glue roller 44 is transferred to the glue coating roller 46, and the glue coating roller 46 The glue on is coated on the bottom surface of the thermoplastic resin layer 2; since a mesh woven reinforcement layer 6 is provided on the lower membrane portion 8, a sufficient amount of glue is required to fill the grid on the mesh woven reinforcement layer 6 with the adhesive layer, and the screw tube 40 is rotated to drive the glue baffle 39 at its bottom to rise and fall along the process groove, and the distance between the glue outlet 38 and the surface of the thermoplastic resin layer 2 is adjusted, so as to control the thickness of the glue coated on the surface of the thermoplastic resin layer 2, and the glue inside the transfer box 35 is coated on the surface of the moving thermoplastic resin layer 2 through the glue outlet 38.

[0061] During the lamination process of the two sets of rubber lamination rollers 19, excess glue on the surface of the thermoplastic resin layer 2 is pressed out, and most of the overflowed glue is synchronously conveyed away by the conveyor belt 76. The glue on the driven conveyor belt 76 is scraped off by the second scraper 79 and falls into the collection box 17 to be collected; the two sides of the decorative film that has completed the lamination are slidably set between the upper connecting plate 80 and the lower connecting plate 82, and are scraped off by the third scraper 81, thereby improving the quality of the decorative film, and the glue scraped off on both sides of the decorative film is retained in the collection box 17 through the guide groove 83 to be collected.

[0062] A slider is provided inside the sleeve 55, and the side of the sleeve 55 slides with the side of the glue storage box 42. The reciprocating screw 51 is a form of a three-dimensional cam pair, which is manifested as two threaded grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw 51, the side of the spiral groove pushes the slider placed in the spiral groove to perform axial reciprocating motion; by arranging a one-way valve on the suction tube 68, the glue in the glue storage box 42 can only be drawn into the piston cylinder 65 through the suction tube 68, and by arranging a one-way valve on the discharge tube 69, the glue in the piston cylinder 65 can only be discharged into the transfer box 35 through the discharge tube 69.

[0063] The glue roller 44 drives the first sprocket 62 to rotate during the rotation process, and drives the second sprocket 63 to rotate through the chain 64, thereby driving the reciprocating screw rod 51 to rotate, and then driving the piston part 53 to slide back and forth, thereby achieving periodic quantitative delivery of glue inside the transfer box 35.

[0064] When the piston part 53 slides in the direction away from the extension rod 70, it drives the piston 67 to slide along the piston cylinder 65 to send the glue into the transfer box 35 through the discharge pipe 69. When one end of the sliding sleeve 55 slides and presses on the corresponding pressure sensor 52, the second servo motor 49 is controlled to start and drive the rotating rod 47 to rotate, so that the semi-guide column 48 rotates to disengage from the ball head 59, and under the elastic force of the reset spring 60, the square rod 58 is driven to slide and rise along the support plate 56, and the ball head 59 is pressed against the side surface of the rotating rod 47. In this process, the first scraper 61 is separated from the scraper plate 54, ensuring the one-way glue removal of the first scraper 61 and the scraper plate 54.

[0065] When the piston part 53 slides in the direction close to the extension rod 70, the glue in the glue storage box 42 is drawn into the piston cylinder 65 through the liquid extraction tube 68. During this process, the first scraper 61 is separated from the scraper plate 54. When the other end of the sleeve 55 slides and presses on another pressure sensor 52, the second servo motor 49 is controlled to start and drive the rotating rod 47 to rotate, so that the rotating rod 47 rotates and separates from the ball head 59. Under the elastic force of the reset spring 60, the square rod 58 is driven to slide and descend along the support plate 56, and the ball head 59 is pressed against the side surface of the semi-guide column 48. During this process, the first scraper 61 slides and descends and presses against the surface of the scraper plate 54. During the process of the piston part 53, the first scraper 61 is driven to scrape off the glue on the surface of the scraper plate 54, thereby improving the use quality of the adhesive roller 44.

[0066] During the reciprocating sliding process of the piston part 53, the guide ball 73 is driven to slide back and forth along the spiral groove 71 on the extension rod 70, thereby driving the extension rod 70 to rotate forward and reverse periodically, and then driving the stirring shaft 36 and the stirring plate 37 to synchronously rotate forward and reverse periodically, stirring the glue inside the transfer box 35, thereby improving the gluing effect.
